About this study

Official title: Double Blind Randomized Controlled Study of the Effect of Botulinum Toxin Injection in Rectus Femoris and Triceps on the Length and the Strength of These Muscles During Locomotion in Chronic Hemiparetic Patients

The aim of this randomized controlled study is to quantify the modification during locomotion of chronic hemiparetic patients of the strength and the length of Rectus Femoris and Triceps Surae induced by botulinum toxin injection type A.

The main hypotheses of this study based on previous studies are that botulinum toxin injection increases on one hand the length of the muscle injected during gait and on the other hand decreased the strength of the muscles injected.

The investigators also hypothesized that botulinum toxin injection improved the strength of the antagonist muscles and normalized the pattern of strength of the muscles injected during gait.

Read the detailed description

The aim of this study is to compare versus placebo the effects of BTX-A injection on :

  • the maximal length of the muscles injected during gait
  • the maximal lengthening velocity of the muscles injected during gait
  • the maximal strength of muscles injected during gait
  • the inter-limb coordination assessed by continuous relative phase
  • the kinematic parameters such as peak knee flexion during swing phase of the gait cycle and peak ankle dorsiflexion during stance phase.

To that end each patient included in the study will be assessed before injection, one month after the BTX-A injection and 3 months after BTX-A injections.

All patients will underwent a clinical examination, a 3D gait analysis and a isokinetic dynamometer analysis.

The comparison of the results in the group treated by BTX-A will permit to show that one month after BTX-A injection peak length during gait of muscles injected, maximal lengthening velocity peak knee flexion during swing phase and peak ankle dorsiflexion increase significantly.

It will also permit to show that the maximal strength of muscles injected decreases whereas the strength of antagonist increases It will also permit to demonstrate that multisite BTX-A injection improve coordination of paretic and non paretic lower limb the inter-group comparison will permit to demonstrate that these modification are mainly due to multisite BTX-A injections.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Measure of the maximal length of the muscles treated by Botulinum

    The maximal length of the muscles treated by Botulinum Toxin during locomotion quantified using 3D motion analysis and musculo-skeletal model.

    This measure will be performed one month after Botulinum toxin injection.

    Measured: 1.5 hours

Secondary outcomes (3)
  1. The maximal strength measure

    The maximal strength developed by injected muscles during gait.

    Measured: 1.5 hours

  2. Inter-segmental coordination measure

    The modification of inter-segmental coordination during locomotion induced by botulinum toxin and quantified by continuous relative phase injection

    Measured: 1.5 hours

  3. Measure of joint torque at knee and ankle level.

    The modification of joint torque at knee and ankle level induced by botulinum toxin injection.

    Measured: 1.5 hours

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing botulinum toxin type A and injection of NaCl 0.9% in people with COMPARISON BETWEEN GROUP TREATED WITH BOTULINUM TOXIN AND PLACEBO, run by Assistance Publique - Hôpitaux de Paris at 3 sites in France.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 30 May 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in France. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Measure of the maximal length of the muscles treated by Botulinum (time frame: 1.5 hours). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01821573, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 May 2019.
